Synopsis

Webmin contains two security vulnerabilities which could lead to a Denial of Service attack and information disclosure.

2. Impact Information

Background

Webmin is a web-based administration tool for Unix. It supports a wide range of applications including Apache, DNS, file sharing and others.

Description

Webmin contains two security vulnerabilities. One allows any user to view the configuration of any module and the other could allow an attacker to lock out a valid user by sending an invalid username and password.

Impact

An authenticated user could use these vulnerabilities to view the configuration of any module thus potentially obtaining important knowledge about configuration settings. Furthermore an attacker could lock out legitimate users by sending invalid login information.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Webmin users should upgrade to the latest stable version:

Code Listing 3.1: Resolution

# emerge sync

# emerge -pv ">=app-admin/app-admin/webmin-1.150"
# emerge ">=app-admin/app-admin/webmin-1.150"
